S4
A Simpler API for Amazon Web Services S3.
It does not implement the full S3 API, nor is that the intention. It just does
the basics (managing files in a bucket) in a very simple way with a
very small code footprint.
Usage
$assets = S4.connect url: "s3://0PN5J17HBGZHT7JJ3X82:k3nL7gH3+PadhTEVn5EXAMPLE@s3.amazonaws.com/assets.mysite.com"
$assets.upload "puppy.jpg", "animals/puppy.jpg"
$assets.upload "penguin.jpg", "animals/penguin.jpg"
$assets.list "animals/" #=> [ "animals/puppy.jpg", "animals/penguin.jpg" ]
$assets.download "animals/penguin.jpg", "penguin.jpg"
$assets.delete "animals/penguin.jpg"
$assets.list "animals/" #=> [ "animals/puppy.jpg" ]
$assets.upload "ufo.jpg"
$assets.list #=> [ "ufo.jpg", "animals/puppy.jpg" ]
Without a URL given, S4 will attempt to read one from ENV["S3_URL"]:
$ export S3_URL="s3://0PN5J17HBGZHT7JJ3X82:k3nL7gH3+PadhTEVn5EXAMPLE@s3.amazonaws.com/assets.mysite.com"
...
$assets = S4.connect
Handy snippet for multiple buckets w/ the same account:
$ export S3_URL="s3://0PN5J17HBGZHT7JJ3X82:k3nL7gH3+PadhTEVn5EXAMPLE@s3.amazonaws.com/%s"
...
$assets = S4.connect url: ENV["S3_URL"] % "assets"
$videos = S4.connect url: ENV["S3_URL"] % "videos"
Low-level access:
$assets.get "animals/gigantic_penguin_movie.mp4" do |response|
File.open "gigantic_penguin_movie.mp4", "wb" do |io|
response.read_body do |chunk|
io.write chunk
puts "."
end
end
end
$assets.put StringIO.new("My Novel -- By Ben Alavi...", "r"), "novel.txt", "text/plain"
Create a bucket (returns the bucket if it already exists and is accessible):
$musics = S4.create url: "s3://0PN5J17HBGZHT7JJ3X82:k3nL7gH3+PadhTEVn5EXAMPLE@s3.amazonaws.com/musics.mysite.com"
Make a bucket into a static website:
$site = S4.connect url: "s3://0PN5J17HBGZHT7JJ3X82:k3nL7gH3+PadhTEVn5EXAMPLE@s3.amazonaws.com/website.mysite.com"
$site.website!
$site.put StringIO.new("<!DOCTYPE html><html><head><title>My Website</title></head><body><h1><blink><font color="yellow">HELLO! WELCOME TO MY WEBSITE</font></blink></h1></body></html>", "r"), "index.html", "text/html"
Net::HTTP.get "http://#{$site.website}/" #=> ...HELLO! WELCOME TO MY WEBSITE...
Plus a handful of other miscellaneous things (see RDoc)...
